IMPROVEMENT IN RLLING SHUTTERS.

Specification forming part of Letters Patent No. 159,3W2', dated February 2, 1875; application filed September 5, 1874.

To all whom 'it may concern:

Be it known that I, HECTOR JOSEPH DE- FRENNE, of Green Bay,in the county of Brown and State ot' Wisconsin, have invented a new and Improved Window-Blind, of which the following is a specification:

My invention consists of a blind made of slats hooked or jointed together, to be raised and lowered by rollers suspended by cords, which pass over an upper roller in a chamber above the window, and down to another roller at the bottom of the chamber, onwhich they wind, said rollers being worked by an endless oord, which is so arranged on pulleys that one part of its course is alongside of one ot' the sides ot' the window-frame, where it can be worked inside otl the house i'or raising or lowering the blind whether the window is open or not, thus affording a more conven; ient means than others now in use for working such blinds. My invention also consists ot' a novel mode of connecting the slats together.

Figure l is an inside elevation of a window with the inside casings removed, showing my improved apparatus. Fig. 2 is a sectional elevation transversely to the wall ot" the building. Fig. 3 is a det-ail section of the blind, showing the mode of connecting the slats.

Similar letters of reference indicate corresponding parts.

Arepresents the blind of slats connected together by articulated joints, so as to pass over or wind on rollers freely to be opened and closed by rollin g up and down. This blind is suspended at the top by cords C, which pass over the roller D in the upper part ot' the chamber E, over the window, and down to the roller F in the lower part of said chamber, to which they are attached, so as to wind on and off for raising and lowering the blind. This roller I prefer to operate by an endless cord, G, which extends from a groove, H, in it down to the lower part of a chamber, I, in the side of the window-frame, onel branch passing under the guide-pulley J, and up to pulley K in the oasin g L of the window-frame, and the other branch passing under pulley M in said casing, so that from K to M the cord will pass inside of the frame and inside ofthe window, where it can be employed for raising and lowering the blind whether the window be open or not. This cord is loaded with weights N for counterbalancing the blind.

I propose to joint the slats together by links O ot' wire laid in a little groove, l?, across the slats, flush with the surface, and coniined by staples Q, and covered by strips ot' leather, It, or other suitable material, extending the whole length of the blind and tacked on the slats, the strips being to conceal the links and grooves and make a smooth surface for the inside paint. These slats will be arranged a little distance apart to admit light, also air for ventilation, it' required. rIhe edges will run in grooves in the sides of the windowframes.

Having thus described my invention, I cla-ini as new and desire to secure by Letters Patentl. The combination of endless cord G, pulley J, and pulleys K M with the blind-operating roller F, pulley J being in chamber I at the side of the window-frame, and the pulleys K M being' in the casing L, all substantially as specified.

2. The slats connected together by wire links O, arranged iu transverse grooves in the slats, and covered by straps It, substantially as specified.
